Last night Leo reported duplicate gnx's after cutting an outline from 
leoSettings.leo to leoPy.leo. I reported the details here 
<https://github.com/leo-editor/leo-editor/issues/158>. This is an extremely 
serious bug.  It's also perversely good news.

Here is the plan:

1. *Discover why the gnx's collided*. The gnx's report that the colliding 
vnodes were created yesterday, 20150320 at 233042. Folks, this makes no 
sense. Imo, a botch in gnx caching likely caused this collision. It's 
*essential 
*to find the cause of this bug before doing anything else.

2. *Permanently activate all gnx checks*, as discussed in this thread 
<https://groups.google.com/forum/#!topic/leo-editor/9STvVMI5Ku4>.

3. *Get rid of the gnx caching scheme!*  It will no longer be needed when 
Leo calls check-outline regularly. Imo, gnx caching is dubious engineering. 
I am so looking forward to killing it.

Recall that gnx caching arose from a bizarre special case in which a Leo 
bridge opens several .leo files within the same second. check-outline can 
handle those special cases. The bridge won't mind the warnings -)

4. *Fix paste-retaining-clones*.  It is fortunate that this issue 
<https://github.com/leo-editor/leo-editor/issues/141> has not yet been 
addressed.

*Summary*: We have come full circle. The problems with the bridge resulted 
in gnx caching. Problems with gnx caching prompted continuous checking of 
.leo files. *Permanent, continuous* checking will eliminate the need for 
gnx caching.  The result will be a simpler, more robust Leo.

This work has top priority: we must test the resulting code for at least 
another work before releasing b1.
